These all refer to the deprecated firmware display driver that isn't used on bookworm. Remove these settings.hdmi_group=2
hdmi_mode=81
framebuffer_width=1366
framebuffer_height=768
Remove the "xrandr --output HDMI-1 --mode 1366x768" too for now, and reboot.
Post the url output from "raspinfo | pastebinit" (when connected to the problematic display) so we can see what we are dealing with.
